I watched a video about Eagle lastly: https://youtu.be/_20gaxHbEAc . Is it possible to do it with Easy-PC version 21 ?
I am asking because Eagle is cheaper than Easy-PC (Easy-PC+libraries). |

Perhaps not as elegant as the Eagle video but YES you can do differential pairs and length balancing in EasyPC.
The way I do it is to firstly establish what track width and gap you need for the differential impedance (you can do this with the calculator utility). Lay down your first differential track at required width. Then using track hugging set to the relevant gap lay in the other track next to the first. Check the track lengths to see which one is the longer and make a note of this. Then using the "head-up" display utility create a loop (or loops) to adjust the length of the shorter track to be the same as the longer. Sounds cumbersome but its not once you've done it a few times.
Note that you can also set up EasyPC to check that the lengths are within a certain length tolerance when doing the design rule check. I certainly wouldn't be choosing Eagle over EasyPC simply for that !

Unfortunately it doesn't measure the whole track length if there is a via and layer change.

It does include a layer change but not the via depth. Normally you would always have both tracks of a pair change to the same layer so the via depths are the same so does not affect the length balancing.

Well it doesn't for me. Is there some setting that's causing this?

Hi John,
The "Tool Tip" gives the overall track length as it is being edited. Otherwise, select all multiple sections of the track, then "Properties" will give you the overall total length (excluding vias!).

Ed,
You also get the full track length in properties as the "Track Length" under the NET tab !

I use Kicad for high speed design. It is nice, easy and free of charge: https://www.youtube.com/watch?v=chejn7dqpfQ
Easy-PC is not state of the art (outdated software).

Hi,
When you examine the cost of Eagle and its limitations for that cost - then Easy-PC is excellent value for money. It may not have every feature, but once you own the license, then the yearly update costs is so much cheaper than the standard Eagle monthly license.
Regards,
Shadders. |

Hardly ! .. updated every year for a very small fee, top notch support, in some cases better than the big boys. EasyPC is professional quality software that I have been using in a professional capacity for almost 20 Years. Free software is maybe ok for amateurs, enthusiasts or students, but when dealing with major business customers you need to be able to rely on the software and the support and that only comes with paid-for tools.

I don't complain about the support. Indeed, the support team is good (bug fixes), but the software Easy-PC is outdated. Most projects have a high speed design. Number one ignores reality. That's it!

I agree there could be more high speed tools, but to fair there is always ways of achieving the same outcome.
Practically all the designs we do here are now high speed and this has never been a major issue.
